' To a/ZZ w22/017e it' may concern:

.repairing the tires o Be itknown that I, JAMES MILLARD PAD- GETT, a citizen of the United States, residing at Topeka, in the county of Shawnee and State of Kansas, haye` invented certain new and useful Improvements in Vulcanizers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. My invention relates to improvementsvin vulcanizers designed articularly for use in fp automobiles and the like while they are on the rims of the wheels and without removing the wheels from their axles.

`One object of the invention is to provide a simple, durable, and eicient device of this l character which may be used upon either disk or spoke wheels and without clamping devices for securing itto the tire.

sys

Another object of the invention is to improve and simplify the construction and op-v eration of devices of thi'scharacter, and thereby render the Same more -eicient in use and less expensive to manufacture.

With the above and other objects in view the invention consists of'certain novel features of constructiom combination, and arrangement of parts, as willbe hereinafter described and claimed. 4

In'the accompanying drawings, Figure 1 is a perspective view of my miproved vulcan- Fig. 2 is a vertical izer set up for operation. longitudinalsectional view through the same, showing a tire m position u on the device.

Fig. 3 is a detail horizonta .sectional view .through the burner, and Fig. 4 is a vertical transverse sectional view through a slightlymodified form of the tire-engaging shoe.-

Referring to the drawings byvnumeral, 1 denotes'a tire-engaging shoe which is adapted` to be supported upon the ground or other suitable support by four legs 2, as shown.

.The shoe in form somewhat resembles a pig,

and its body portion 3 is curved longitudinally l and transversely to conform to the shape of the tire which'it is adapted to receive, as seen in Fig. 2 ofthe drawings. The shoe is preferably cast of aluminium or other-suitable metal and 'has upon the outer face of one Vof its sides a recessed projection fl, in which a thermometer 5 is mounted.

The legs 2 support ythe body of the shoe a suflicient distance from the ound to.permit a heating device 6 to be disposed beneath the pody and longitudinally between the said' egs. the form of a gasolene-burner and, as shown,

comprises a mixer and burner-tube 7, which unites said'end of the tube to one end of an oil-supply pipe 11. The oil-supply pipe 11 extends parallel with the tube 7 and is adapted to have its end adjacent to said connection T110 heated by flames which are projected This .heating device-is preferably in V against it from outlet-openings 8a, formed vin the adjacent side :of the tube 7, as clearly' shown in Fig. 3 of the drawings. The gas thus generated from the oil in the pipe 11 passes into the connection 1() and is discharged therefrom into the open end of the tube 7 through a needle-valve 13, which is provided in said connection. j

In order to generate gas when the burner is started, the depending portion of the connection 10 is provided With an oil-cup 14. When a little oil is burned in this startingcup, it will quickly heat the outer end of the pipe 11 andthe connection 10 and generate suflicient gas to start the burner.` The outer end ofthe oil-supply pipe 1 1 is bent upwardly and at right angles toits body portion and is secured to the lower end of a gasolene-supply -can or receptacle 15, which is supported uponv a leg 16, provided upon its bottom. This can 15 has a screw-threaded neck 17, which is closed by a screw-cap 18. i l

In using the vulcanizer `the tire is prepared for vulcanizationin the usual manner and is placed upon the shoe so lthat the portion to be mended is within the latter, the weight of the machine being vsuflicient to hold the'tire firmly upon the shoe. The heatingv device is then placed beneath the shoe, so that the llames from its burner will strike the bottom of the shoe between its supporting-legs, and' the burner isy then started.' By operatmg the needle-valve of the burner the size of the ame, and hence the amount of heat, may be ICO readily controlled. It will be seen that the device is adapted for use upon either disk or spoke wheels and that it is particularly well/ In Fig. 4 of the drawings I have shown a slightly-modified form of the tire-engaging shoe. In this form it will be noticed that the body 3 of the shoe is made hollow to form a heat chamber or space 20. Heat from the burner is admitted into this space through a longitudinally-disposed opening formed in the center of the bottom of the shoe and after pressing upwardly through the chamber or space 20 escapes through outlet openings formed in the top of the sides of said shoe, as shown. The construction and operation of this form of the invention are in other respects similar to the construction and operation of the form of the invention irst described.

While I have shown and described the preferred embodiments of my invention, it will be understood that I do not wish to be limited to the precise construction herein set forth, since various changes in the form, proportion, and the minor details oi construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure byLetters Patent, is-

1. rlhe combination of a tire-engaging shoe formed hollow to provide a heat-chamber having an inlet at the center of its bottom and outlets at the top of its sides, legs for supporting said shoe, and a heater disposed beneath said shoe and adapted to discharge heat into the inlet of said heat-chamber, substantially as described.

2. In a device of the character described designed for the purpose of repairing tires without removing them from their wheels, comprising a tire-engaging shoe of semicircular cross-section and supported upon short legs, an aperture at one s1de of said shoe, a thermometer in said aperture, an oil-supply pipe passing under the shoe, a connection 10 secured to said supply-pipe and provided with a needle-valve, a combined mixer and burner secured to said connection in line with the needle-valve and provided with openings at the side and top for the urpose described, and an oil-cup under said) connection, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
